IDEA: To find more employees who work for your customer, search the customer name on Linked-In to get names, employee titles, length of employment and other info.

If you are trying to find other employees that work at your customer, go to LinkedIn and search the customer name.  Chances are many of them are listed on LinkedIn with their correct employer name with their page.  The search will show their name and title with the company and how long they have been there.
